🎏 Is Non Nano Zinc Oxide Safe

Nope. Like all UV filters, zinc oxide needs to stay on the surface of the skin to protect it from the sun. If it penetrated your skin, then UV rays would get through too and cause all sorts of havoc. In other words, an UV filter that penetrates skin is useless. That’s why cosmetic chemists often coat zinc oxide nanoparticles with silicones The presence of either micro- or nano-sized zinc oxide caused significant small-molecule photodegradation and the degraded mixtures exhibited higher levels of toxicity in embryonic zebrafish assays. This study suggests that caution must be taken when formulating sunscreens containing both zinc oxide and small-molecule UV-filters to avoid Non-Nano Zinc Oxide 10. Non-nano zinc oxide refers to a type of zinc oxide—a powdered mineral used in sunscreens to protect the skin from UVA rays and UVB rays. Traditional zinc oxide is composed of nanoparticles. These nanoparticles are so tiny, that they’re measured in billionths of a meter and are invisible to the naked eye. Raw Elements Face Stick All-Natural Mineral Sunscreen | Non-Nano Zinc Oxide, 95% Organic, Very Water Resistant, Reef Safe, Non-GMO, Cruelty Free, SPF 30+, All Ages Safe, Moisturizing, 0.5oz $14.99 $ 14 . 99 ($29.98/Ounce) Uses non-nano zinc oxide or titanium dioxide. Generally, sunscreens that use these two main active ingredients are considered to be reef-safe. Nano particles can be ingested by marine life (including coral) causing internal damage. Does not include: oxybenzone, octinoxate, octocrylene, butylparabens, avobenzone, homosalate. Zinc Oxide (ZnO): Studies have found that even low concentrations of ZnO may lead to damage in human epidermal cells. Yet, a review of the risks of nano-structured TiO2 and ZnO found nanoized TiO2 and ZnO are not likely to penetrate the skin due to how they are bound. The researchers concluded both materials are safe to use as UV filters. This does have zinc oxide. But it’s non-nano. Micronized zinc oxide should be avoided. Remember we talked about the nano-particles being more toxic. Again, this form in non-nano. Zinc oxide is used as an effective broad-spectrum sunblock. And the other great feature about this product is that it comes in an eco-friendly cardboard container! Zinc Oxide (non-nanoparticle) is considered very safe. It’s the primary ingredient in zinc cream / nappy rash cream, and it’s been used medically since at least the first century AD as described by the greek physician Dioscorides. It’s a white, stable mineral powder, so no preservatives are required to be added to protect it or stabilize it. Ks3b1.
